I'll be the first to admit that I like it when we get classic Sims elements back, with an expansion, or store content, but only in small doses. I don't think everything should be exactly like Sims 2, nor do I think, besides Pets, Weather, and a Teen Style stuff pack, is worth repeating. I think Sims 2 was special, because of the gameplay Sims 2 had, and I think Sims 3 is special because of the new game play it will bring, and has brought in the future. Even Seasons and Pets have to be upgraded and different from Sims 2, otherwise what would be the point of having them in Sims 3?
As far as cookies, and baking goes, I'd like to see different types of cookie recipes avaliable, not just chocolate chip. Maybe oatmeal raisin, or peanut butter could serve as a possible recipe choice? I'd like it if adults could bake the different sweets children can bake in the toy oven as well!
